I'm looking at a site that ranks #1 in google for some keywords. I looked over the code of the sites that link to them using ahrefs.com and I came upon something interesting that I don't understand:
For siteA1, they have 5 or more pages (shipping, terms & conditions, sitemap etc) that link back to the web design firm that did their site. EX: siteA1.webdesignfirmSiteB.com/sitemap and this 301 redirects to siteA1.com/sitemap.
For another site siteA2, they have a lot of links that do the same thing. EX: siteA2.webdesignfirmSiteB.com/blue-widgets/ 301 redirects to siteA2.com/blue-widgets/
Is this cheating the ranks?
